OVEN GRID.

Application filed June 1,

This invention relates to oven grid construction. V

In oven grids, as heretofore constructed, it has been the usual practice to provide guides rigidly fixed within the ovens upon which the grids or pans slide. .Obviously,

when these gridsare pulled out they are 'fre-- quently pulled entirely out of the grooves due to their sticking action, which causes a, jerky sliding action. Further than this, as the grids or pans arepulled out they necessarily sag down at an angle.

This invention is designed to overcome the above noted defects, and objects of such invention are to provide a novel construction of grid for ovens which is so organized that the grids are at all times fully supported in the grooves, although they are-moved outwardly from the oven itself, and to provide a very simple and easily operated construction forattaining these results.

Further objects are to provide a grid construction which permits the freer handling of the materials baked in the oven without danger of burningthe operators hands, so

the articles cooked in the oven may be presented outside of the oven so that they may be freely removed or inspected.

An embodiment of the invention is shown in the accompanying drawings in which Figure 1 is a longitudinal sectional view through an oven equipped with the grid de-. vice, such view corresponding to a section on the line -1-1 of Figure 2;

Figure 2 is a fragmentary, transverse, sectional view on the line 2.2 of Figure 1.

Referring to the drawings, it will be seen that a usual or conventional type of oven is indicated by the reference character 1, and is provided with a door 2, hingedly mounted on the oven, for example, adjacent the lower portion thereof.

The grid construction comprises a plurality of parallel channel members 3 positioned on opposite sides of the oven and arranged in a regular sequence and adapted to receive the grids proper, or the pans or other members of this type. These. channel members are not rigidly secured to the ovenvas has heretofore been the practice, but are rigidly secured to upright supporting bars 4 and 5 located adjacent the front and rear of the oven and on opposite sides thereof. These bars are respectively carried by the upper ends of links 6 and 7, which are arranged in pairs on opposite sides of the oven. One set 1926. Serial No. 112,910.

of links, for instance, the forward set 6, is rigidly attached to a rock shaft 8,-which pro ects outwardly from the oven, as shown in Figure 2. This rock shaft carries a manipulating crank 9 provided with a' handle 10.

and thereafter the crank or handle is rocked forwardly, thus moving the links into their dotted line position, shown in F igure' 1, and consequently rocking the supporting channel a i In using the device, the door 2 is opened members 3, and the grids carried thereby outwardly to the dotted line position of such figure. It is to be noted that in this forward position, the members rest upon the door and bottom of the oven and are thus in a very stable position. Further, when the device is rocked into its normal position, as shown in full lines in Figure 1, the rear bar 5 and the rear ends of the channel members 3 abut the rear wall of. the oven and thus retain the members firmly in position.

. It will be seen, therefore, that a very simple and serviceable type of grid construction for ovens has been provided which may be easily manipulated'to move the members outwardly from the oven for inspection or removal, so that the utmost freedom is afforded the operator without the usual danger of burning the hands in the handling of the materials baked in the oven.

Although the invention has been described in considerable detail, such description is intended as illustrative rather than limiting as the invention may be variously embodied and as the scope of such invention is to be determined as claimed.

I claim;

1. The combination of an oven having bottom, top, back, and side walls and having an open front, a door for said open front,

two pair of levers mounted within said oven and located on oppositesides thereof and pivoted adjacent their lower ends, a plurality of vertical bars suspended from'the upper ends of said levers, channel members carried by said bars for the reception of a grid, a transverse rock shaft secured to certain of said levers and projecting through a side wall of the oven, a manually operable lever secured to said rock shaft and located on the outer side of said oven, said levers being adapted to occupy either of two .positions on opposite sides of-dead center, one position with the channel members within the oven, and the other position with the certain of said vertical" members when in the last position resting upon the bottom of the oven and locking the parts against further outward motion.

2. The combination of an oven having a bottom, top, back and sidewalls and having an open front, a door for said open front, two pair of levers mounted within said oven and located on opposite sides thereof. and pivoted adjacent their lower ends, said levers forming a rear pair and a front pair, a pair of vertical members suspended from the upper ends of each pair of' levers, a plurality of rails carried by said vertical members for the reception of grids, a'i'ock shaft extending across said oven and located on the outer side of said oven, the.

pivot points of said levers being so located as to cause levers to swing past dead'center a slight distance when in their rearmost position, whereby when said manually operable lever is rocked forwardly said rails will travel approximately horizontally for a material distance and thendownwardly past dead center.

In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee, in the county of Milwaukee and State of Wisconsin.
